Millions of people keep this cheap painkiller in cupboards and handbags without knowing a hidden health risk11:22, 29 May 2026Many people rely on a cheap everyday painkiller to get through headaches, back pain and aches and pains without giving it a second thought. But health experts warn the common medicine may come with a little-known risk that can become more serious the more frequently it is taken.‌The drug, which can cost as little as 35p in supermarkets and pharmacies across the country, is used by millions across the UK every year. While many people take it occasionally without issue, research suggests regular or high-dose use could raise the risk of serious heart problems.‌Ibuprofen belongs to a group of medicines known as non-steroidal anti-inflammatory drugs (NSAIDs), which are commonly used to reduce pain, inflammation and fever. According to the NHS, side effects can include nausea, indigestion and headaches, though more serious complications can occur in some people.‌The NHS warns people should seek urgent medical help if they experience symptoms including chest tightness, trouble breathing or signs of a heart attack after taking ibuprofen. Guidance also states the medicine may not be suitable for people who have high blood pressure, coronary heart disease, heart failure or circulation problems.According to research highlighted by Harvard Health, taking certain NSAIDs daily — including ibuprofen — was linked to a 20 to 50 per cent higher risk of heart attack compared to people not taking the drugs. The report, published in The BMJ, found the risk could begin increasing within the first week of use, particularly at higher doses.‌Harvard Health said the “most harmful doses” appeared to be more than 1,200mg of ibuprofen per day. Experts added that while the overall risk for healthy people remains relatively small, it becomes more concerning in older adults and those with existing cardiovascular conditions.Another Harvard Health report explained that all non-aspirin NSAIDs appear to carry some degree of heart risk. It added that the longer the drugs are taken and the higher the dosage, the greater the potential danger becomes.The NHS advises adults should not take more than 1,200mg of ibuprofen a day without speaking to a doctor. It also recommends taking the lowest dose needed for the shortest possible amount of time.‌According to the Mayo Clinic, the increased risk of heart attack and stroke affects both people with heart disease and those without it. However, specialists say the risk is greater in people who already have underlying cardiovascular problems.Harvard Health has also pointed to evidence suggesting NSAIDs may increase blood pressure and cause fluid retention, which can place extra strain on the cardiovascular system. Researchers say this may partly explain why long-term or high-dose use has been associated with heart attacks and strokes.Article continues belowHealth professionals stress people should not suddenly stop prescribed medication without medical advice. Anyone worried about side effects or needing regular pain relief is advised to speak with a GP or pharmacist about the safest treatment options available.
